Can Two Fantail Goldfish Live In A Ten Gallon Tank?

Our local pet store is having an inventory sale and everything is 50% off. My mom got me two fantail goldfish, about the size of a quarter. I guess the people that worked there where clueless because they advised that they live in a small 2.5 gallon plastic tank. My mom just got them for me as a surprise, I had no idea she would so this. So the two fish lived in that small plastic bowl for about a week until I could scrape together the cash for a proper set up.

I went to the pet store yesterday and picked up a ten gallon tank with an Aqua Clear filter, a canopy with a 13 watt bulb, three plants, two bags of rocks (4.4 lbs), and a solid castle ornament.

So I set up the tank and added the water conditioner, waste control, and cycle to the tank. Then I added the two fish. They are happily swimming around and it seems that they have tons of space. Each fish is about an inch long, maybe less. So can they live in this set up? If so, for how long? I remember reading that all types of goldfish need at least a 20 gallon tank, but right now they have alot of room. What do you think?

    Maybe for now (since they’re little), but eventually they will both be too big for the tank. A ten gallon tank is too small for even one goldfish. Better off with a 20 gallon tank for ONE fish.

    EDIT: The “one gallon per inch of fish” rule isn’t very good to go by. Especially with goldfish, since they produce a lot more waste per fish. Use common sense. You don’t want to put a 10 inch fish in a 10 gallon tank because it won’t have any room.

    The rule I always heard is one gallon of water for each inch of fish. So you could have 10 one inch fish, or 5 two inch fish or 1 great big fish.

    everyone is going to say whats wrong with you goldfish need a bigger tank. now to hell with them becaue i have 4 common goldfish in a 10 gallon tank and they have lived there for 1 and a 1/2 years. but also if you do have the money i will suggest geting a cheap 35 gallon tank at walmart tank there like 25-30 bucks just clean it up and put the fish in there and they will be so happy

    As long as the filtration is coping this will do as a temporary stepping stone. You will have to do water changes every other day though as tanks cannot cycle instantly – those cycle products are a bit of a con really!

    Start saving for the bigger tank with a bigger filter, Goldfish do the majority of their growing in the first 1-2 years of life.

    The fish will only grow as big as the tank allows them to, and if you’re keeping the tank clean then it shouldn’t be a problem.
    I had 3 fan-tails in a ten gallon tank for two and a half years.

    I have a 10 gallon tank with a Lionhead, a fantail, a common goldfish and a minnow, and they’re all doing fine. I’ve had my Lionhead now for about 3 years. So you’ll be fine with having two in a ten gallon tank. If they start to get really big though, you might think about getting a bigger tank. But I wouldn’t really worry.

    I agree completely with catx. 10 gallon is an alright temporary tank. Save up for a tank that’s around 30 gallons (20 for the first fish, 10 for each goldie after that).

    Add a dose of your Cycle every day until you know for certain that your filter can handle it.

    a 10 gallon is fine. my rule is 3 goldfish per 10 gallon. cause that seems just right. now if they are large goldfish then no a 10 gallon is not right. but since they are small it works.
